Our refurbished stoves are graded according to their appearance. All stoves are in perfect working condition and all necessary parts have been replaced. A+ stoves have cast iron bricks inside the fireplace. This stove is the nearest to the original. All enamel is original. A/G stoves are also in good condition, although some damaged enamel may have been sandblasted and painted black (as we are not able to re-enamel). They have baked bricks inside the fireplace instead of cast iron. Baked bricks will have to be replaced more regularly as it burns through quicker from the heat than cast iron. B/G stoves also have baked bricks. The appearance of these stoves is slightly affected by the refurbishing process. Some parts may have been refurbished rather than replaced, which leaves marks (such as from welding). The stove is still in perfect working condition, as this only affects the appearance and not the function of the stove.
